Re: Dealing with Rust
Most effective method for dealing with rust is to remove the paint and then treat it with a phosphoric acid solution. There are phosphoric acid rust removers with zinc that are effective especially in welded seams . It dissolves the rust and leaves his Zinc film. Panels treated like this they can stay indoors for a year without re rusting. Two coats of a aluminum pigmented permanent rust sealer Do not use black follow it up with any kind of primer you want over that and then your color. By utilizing a phosphoric acid solution and top coating with an airtight seal you have done everything humanely possible to prevent rust.

I could cut the cowl apart for access and weld it back together, but I it's just surface rust and not rusted through. Hate to risk more harm than good. |

Re: Dealing with Rust
Scuff it, wipe clean with a wax and grease remover then apply a good quality epoxy primer as per manufacturers directions and call it perfect. No other work required.
